Bovine endometrial organoids: a new tool to study conceptus-maternal interactions in mammals†.
Article in Biology of reproduction, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We developed a hormonally responsive organoid model of the bovine endometrium. Bovine glandular epithelial cells isolated from reproductive tracts were cultured in an extracellular matrix hydrogel (Cultrex 2) at 38.5°C, 5% CO2 (n = 3). RNA was extracted and qPCR confirmed the presence of gland markers: leukemia inhibitory factor, mucin-1, insulin-like growth factor binding protein-1, kruppel-like factor-5, and forkhead box protein-A2. Organoids were imaged at specific time-points to monitor growth. Morphologically, organoids were spherical and fast-growing at passages 0 and 1, but this declined following passage 2. Passage 0 (n = 3) organoids were treated with 1000 ng/ml recombinant ovine Interferon Tau (IFNT) or 10 μg/ml progesterone (P4) for 24 h and analysed by RNASeq to assess hormone responsiveness. 373 transcripts were upregulated (padj<0.05 or log2fold change >2) in response to P4 treatment, with downstream analysis showing significant overrepresentation (FDR < 0.05) of genes associated with positive regulation of protein localisation to plasma membrane and cell periphery. Of the 240 genes significantly downregulated by P4 these were significantly overrepresented (FDR < 0.05) in biological processes of cilium and cytoskeleton organisation. IFNT treatment resulted in significant upregulation of 414 genes and downregulation of 119 genes. The largest cluster associated with differentially expressed genes in response to IFNT is defence to virus and interferon signalling. Thirty genes were altered by both P4 treatment and IFNT treatment. Organoids were also shown to express conserved microRNAs, and it was possible to culture them in a microfluidics device-making them a useful model for a multitude of potential investigations. Bovine endometrial organoids are therefore a new tool to investigate conceptus-maternal interactions.
